A36 03 In-position Flag ON: In position
OFF: Not in posi-
tion
Turned ON at following times:
• When pulse output to error counter is
stopped and absolute value of error
counter present value is less than in-
position range
Turned OFF at following times:
• When pulses are being output to error
counter
• When absolute value of error counter
present value is greater than in-posi-
tion range.
• When power to CPU Unit is turned ON
• When CPU Unit operation starts
• When CPU Unit operation stops
This flag is used as
an NO condition
when clearing the
frequency com-
mand value to zero
from the user pro-
gram.
04 Error Counter Error
Flag ON: Error counter
error
OFF: No error
Turned ON at following times:
• When pulse output to error counter is
stopped and absolute value of error
counter present value is greater than
or equal to error counter error detec-
tion value
Turned OFF at following times:
• When error counter error is reset
• When power to CPU Unit is turned ON
• When CPU Unit operation starts
• When CPU Unit operation stops
This flag can be
used to provide
notification of
excessive pulses in
the error counter,
e.g., when manu-
ally moving the
motor shaft while
positioning is
stopped.
05 Error Counter Pulse
Output Flag ON: Pulses being
output
OFF: Pulse output
stopped
Turned ON at following times:
• When pulse output to error counter is
started
Turned OFF at following times:
• When pulse output to error counter is
stopped (including immediate stops
and deceleration stops)
• When power to CPU Unit is turned ON
• When CPU Unit operation starts
• When CPU Unit operation stops
This flag is used to
determine whether
pulses are being
output to the error
counter.
This flag can be
used to determine
when internal pulse
output has been
completed and
start the next
instruction.
06 Error Counter Pulse
Output Acceleration/
Deceleration Flag ON: Pulse output
to the error counter
is accelerating or
decelerating (i.e.,
the frequency is
changing)
OFF: Pulse output
to the error counter
is constant
Turned ON at following times:
• When pulse output frequency to error
counter is changed by ACC or PLS2
instruction
Turned OFF at following times:
• During output of a constant pulse fre-
quency to error counter
• When pulse output to error counter is
stopped (including immediate stops
and deceleration stops)
• When power to CPU Unit is turned ON
• When CPU Unit operation starts
• When CPU Unit operation stops
This flag is used to
detect changes in
the output fre-
quency when the
frequency is
changed stepwise
for internal pulses
are being output by
the ACC or PLS2
instruction. It can
be used as a condi-
tion for executing
ACC or PLS2 dur-
ing internal pulse
output.
